1 Purpose

F01VBF (ZTRTTP) copies a complex triangular matrix stored in full format in a two-dimensional array to packed format in a one-dimensional array.
Packed storage format is described in Section 3.3.2 in the F07 Chapter Introduction.

2 Specification

3 Description

F01VBF (ZTRTTP) packs a complex n by n triangular matrix A, stored conventionally in a two-dimensional array into a one-dimensional array of length nn+1/2. The matrix is packed by columns. This routine is intended for possible use in conjunction with routines from Chapters F06, F07 and F08 where some routines use triangular matrices stored in the packed form.
